Pneumatic Starting Systems Flashcards
Why are air-turbine starters superior to electric starters for large turbine engines?
They are light weight for the torque they produce
Where does an air-turbine starter get its air for starting the engines in a jet transport airplane?
From an APU, GPU, or from a running engine
What is the purpose of the shear section in an air-turbine drive shaft?
If the ratchet mechanism fails to release and the engine drives the starter to a speed higher than its design speed, the shear section will break and disconnect the starter from the engine
What prevents too high an air pressure from overspending an air-turbine starter?
The air shutoff and regulating valve
Where does an air-turbine starter get it lubricating oil?
It has a self contained lubrication system with the oil held in the starter housing
What device in an air-turbine starter warns a technician if there are any metal chips or particles in the oil?
Magnetic chip detectors warn of any metal contamination in the oil
